Applieation filed Iebruary 13, 1889. Seral No. 299,766. (No model.)

T aZl wh0m it may concern:

Be it known that I, J OHN CAULFIELD, a citizen of the Uniced States, residng at South Bend, in the county 01": St. Joseph and State of Indiana, have nvent-ed eertain new and useful Improvements in Car-Doors, of which the followng is a speefiea'ron, referenee being had therein to the aceompanying drawmgs.

Ths invention relates t0 certain improvements in cars,bnlclings, and other structures of any clescription in whieh a sliding door 0r gate is employed; and it has for its objects to simplify the construeton of the door or gate, t0 provde for applyng it 130 the struet nre without materially cleparting from the usual constrnation thereof, 00 dispense With the usual battens for strengthenng the door, and provide a door wheh,when opened,will, with all of ts parts, be entrely out of the way, so that the parts may 1101; he injured in loacling 01 unloading the ear, 0r rnoving artic1es in or out of the struetnre, as will be more f ully hereinafter set f0rth.

My nventon further has f0r iis 0bj eets to prevent the entranee of water 01 snow into the ways in which the sliding 0r telescoping rails of the door trave1.

The above-mentioned objects I attain by the means illustratecl in the aecoinpanying drawings, in whieh= Fgure 1 represents a sde elevation of a portion of a freight-ear, showng my door applie. thereto in a elosed poston. Fig. 2 represents a longitudnal horizontal sectonal view of one sicle of a aar, showng the door in position elosecl. Fig. 3 represents a partial side elevation and sectional wew of the door and spring-latch 0.1 fastening device of the same. Fig.4 represents a transverse vertieal sectional view taken 0n the1ine 00 03' of Fig. 2. Fig. 5 represents a simlar view taken on the lne a: of Fig. 2 Fig. 6 represents a similar view taken on the line 0: 0: of Fig. 2. Fig. 7 represents a perspeetve view of the nteri0r of one side of a grain-ear, showing my nvention applied thereto; ancl Fig. 8, a longitudinal seetional view of one side of a of the ear in the ordinary manner.

grain-ear, sh0wing a modifieation of my nvenuion.

Referring to the clrawings, the letter A inclieates the body of a freight 01 grain car of the orclinary eonstruetion, having; tl1e usual openings at the sicles f0r 1ading and unloading 'phe same.

The letter B indieates the veriical posts f0r1ning a p0r'uion of the frame-werk of the ear, and 0 the 0ute1 sheaching 01 sidng thereof, whieh is built upon the frame-work In the sad siding 01 sheathing, on the inside, near the top and b0tto1n shereof, are for1ned longitudinal parallel slots -01 grooves D. In the grooves 0r reeesses D are loeated longitudinal metallic casings F, whieh in the present instance are rectangular in cross-section, and whieh are providecl wth flanges orlips G, extencling ontwardly throngh the s1ots D,

' where they are bent at right angles nto rabbets at the edges of the slots, s0 as to be flnsh With ihe outside of the car, forming a smooth and clurable way through whieh the web of the sliding 01 teleseoping rail may travel.

The letter II indieates the rails, whichare similar in eross-seetion to the orclinary T-rail in use on railroads, ancl which are atiaehed to the nner sicle of the door A at its fianges by means of serews 01 other fastenng devices, IJl1e fianges setting in recesses in the said inner side of the door, s0 as to be flush themwith. The erowns K of the rails are arranged t0 slide back and forth in the casingF as the (1001 is openecl 0r elosed, s0 as to support t ancl guide it in its travel. The outer end of the crown of each rail is proviclecl With a rightanglecl extenson L, whieh enters tl1e s0eketed plates M, seenrecl 'to one of the door-posts, When the (1001 is elosecl, and h0lds the door at chat sicle against lateral displacernene f rom pressure 011 the inside of the car. The enter the easings, so as to permib the rails move therein with the least possible amount of frieti0n. The easings are seeured '00 the upright studding of the frame by means of screws, bolts, or other similar fastening devices, as indeated by the letter T in Fig. 7, S0 as to be held seeurely in their seats.

is used in conneetion With the door A when the ear is to be employed f0r earrying grain in bulk, the said door having a rail II al:- taehed t0 i'os enter face, whieh slides inaeasing F having icsright angled extensions passing through a slot W in the inner wall 0r sheathing of the aar, the easing being seated in a reeess X in the back Wall of said sheathing, similar to the recesses D, before mentioned. The erown of the rail of the door U is provided with a right-angled extension L, in the samemanner as the rails of the door A, which enters a soeket-plate M in the doorpost when the said door is elosed. The casing in which the rail of the door U slides has at its ou-ter end a reeess N, in. whieh the right-angled extension L sets When the door is drawn back, s0 as to be out of the way;

The heads of therails II each extend back of the rear edge of the door a suifieienl; dishanee to cover the slots from the inside, as shown at H, to prevent the entranee of water 0r snow to the easings Where the outside doors areused, or the entranee of grain into the Same in the case of the inside grainconfining doors. The casings F are also extended, as shown al; F, to receive the extensions H when the door is open, this extension of the casing being, als0 embedded in grooves in the aar-body.

The letter V indieates a latch whieh is piv oted to the outside of the enter door near 0ne edge thereof. The said lateh projects beyond said edge and. has a hooked end Z, whieh is adapted t0 pass through a staple A secured to the stop B, attaehed 00 the outside of the ear.

The lateh V is arranged te werk within a guide-plate O upon the outside of the door to whieh said guide-plate is secured. Above the guide-plate is seeured a similar plate D, whieh is provided With a sliding bolt E,

werking through openings in the upper and lower parts of the upper plaue and the upper parirof thelower plate, the lower end of said bolt hearing against the upper edge of the latch. The bolt is surrounded by a spiral spring F, whicl1 bears against a pin G (pass ing through said bolt near its lower end) and against the upper end of the plate D, s0 as to keep ohe latch pressed normally down to eause the lateh t0 automatically engage the staple when thedoor is elosed. Thefree edge of the lateh is beveled 01 eurved,so as to automatically enter the staple, and is provided with an aperture for the reeeption of a hasploek 1, by means of whieh the door may be seeurely fastened when closed.

As sh0wn in the modifieation illustrated in Fig. 8 of the drawings, the door U is construeted of sheet metal, and is arranged t0 slide in a reeess in the inner faee of the sheathing, s0 as to be flush with said face and out of the way when loading the car. The letter U indicates a sliding door, whieh The operation of my invention Will be read ily understood from the above without further deseription.

I-Iaving thus deseribed my invention, whatI claim, and desire 00 secure by LettersPatent, 1s-
